Ignition of bluff-body methane flames
The movies show the ignition process following a spark in a bluff-body stabilised methane non-premixed flame. The flow is described in: S.F. Ahmed, R. Balachandran, T. Marchione, E. Mastorakos, Spark ignition of turbulent nonpremixed bluff-body flames, Combustion and Flame 151 (2007) 366–385 doi:10.1016/j.combustflame.2007.06.012. The Large Eddy Simulation movie is due to A. Triantafyllidis; the paper will appear in Combustion and Flame (2009).
